ACETYLENE GENERATING AND STORING APPARATUS;

Application filed June 14, 1911.

T 0 all whom it may concern:

Be it known that .I, GHAnLEs FRANCIS JENKINS, a citizen of the United States, residing at 1808 Bark road northwest, Washington, in the District of Columbia, have invented certain new and useful Improvements in Acetylene Generating and Storing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to acetylene gen; erating and storing apparatus and the emin detail sets forth devices especially intended for use on automobiles or other vehicles.

The general object is to provide a com.- .pact, inexpensive apparatus which while effective is safe even in the care of the most unskilled persons. In general a small steel storage tank is provided Withya removable generator 1n which Is placed, /fromt1me to time, a hunted amount of water and a carbid cartridge containing only sufiicient car-K bid to fill the tank with gas at, a safe pres sure; Provision is alsomade for/automatically ,and harmlessly discharging anyQgas that may be in the It nk when the generator is removed. v I

In the accompanying drawings, Figure 1 is a side elevation, partly /in aiiial section, of an acetylene storage tank of common gen eral form. Fig. 2 is an enlarged view showing in axial section a generator. seen-in Fig. l in placein the tank. f

- In these figures, A represents a seamless 'steel, horizontally placed, tank provided -with a discharge or la'mp-supply ,pipe 'B having a valve C and communicating with a pressure gage D. Into the wall of this tank is screwed a cylindrical generator tube E, preferably, as shown, axial with respect to the tank and projecting intothe same from one end. This tube is closed at one end by a permanently attached cap F.

threaded at Fto engage in a threaded aperture in the tank, provided with a circumferential fiangeF .a gasket F and adapted to receive a wrench or the like by which it may be screwed into place in the tank or be detached therefrom. The opposite end of the tube is closed by a threaded cap G also adapted to be rotated by a suitable tool. The tubeis divided transvcr sely by a f0- Specification of Letters Patent.

raminous diaphragm H, and is provided, 'between the diaphragm H and cap F with a stall, open tube I extending inward approximately to the axis of the tube. The tube is also provided with an aperture J leading outward through its wall near the flange F of the cap.

To prepare the generator for use, the cap G is removed, the'aperture J is closed, if desired, and while the tube is held erect water is placed in the tube, any surplus escaping through the small lateral tube 1, a carbid cartridge K, preferably of paper, is then placed upon the diaphragm and the cap G is replaced, and the whole generator is screwed firmly into the tank A, as shown in Fig. 1. v

The parts are so proportioned and arranged that in any position of the tube little or no water will escape through the Gas is at once generated, filling the upper part and then escaping through the pipe I- "into the tank, whence it passes to the lamps in the usual way. Each cartridge contains enough and only enough, carbid men the tank properly and hence there is no danger om over-generation. y

,When the gag'e shows that the gas is nearly exhausted, the generator is removed and refilled. Danger is here avoided by means of the aperture J which is safely closed when the generator is screwed liti -me in .the tank wall but which is opened as soon as the generator is partly unscrewed and while it is still safely held by the threads. If then gas under material pressure fills the tank when the detaching operation begins, it escapes harmlessly between the flange and tank wall. It is obvious that changes in construction may be made while keeping within. the invention, and I do not wish therefore to limit myself to the construction shown.

'What I claim is:

The'combination with a gas storage tank having a suitable threaded opening. of a tubular water holding generator projecting inward through said openin and having its outer end portion in threa ed engagement in said opening, a foraminous wall dividing the generator transversely and forming in one end thereof a carbid compartment, an and opened by partially unscrewing the open tube passing outward through the Wall same. 10 of the body of the generator from a point In testimony whereof I affix my'signature in the axial portion of its interior, the apin presence of two witnesses.
